DETAILED DESCRIPTIONS

To further illustrate, embodiments detailing a fishing reel are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.

Example 1

The disclosure provides a fishing reel comprising a frame 1. A reel seat 2 is disposed in the frame 1 and comprises a central through hole. A spool 3 is disposed on the reel seat 2 for winding a fishing line. A main shaft 4 is slidably disposed in the central through hole of the reel seat, and comprising a first end and a second end. A roller 5 is disposed on the first end of the main shaft. A first gear 6 and a second gear 7 are both disposed on the second end of the main shaft 4 in the frame 1. The first gear 6 is engaged with the second gear 7 and is greater than the second gear in diameter. A handle 8 is disposed on the frame 1 and is connected to the first gear 6 in a transmission way. The second gear 7 is disposed around the main shaft and is connected to the main shaft 4 in a transmission way. A release button 9 is disposed on the frame 1 and is configured to push the main shaft to move forward. A first pressure spring 10 is disposed between the second gear 7 and the main shaft 4 to push the main shaft 4 to abut against a control end of the release button 9.

A cam unit 15 is disposed on one end of the reel seat 2. The cam unit 15 comprises a bearing 16 and an end cover 17. The bearing is disposed on the one end of the reel seat 2 and limited by the end cover 17. The end cover 17 comprises a first end in threaded connection to the reel seat 2, and a second end provided with a cam (not shown in the figures) disposed on the bearing 16. The cam comprises a first edge comprising a first circular surface overlapping the circular surface of the bearing, and a second edge comprising a second circular surface contracted towards the center of the bearing 16; and the first circular surface is connected to the second circular surface through smooth transition.

A hook-shaped line guide seat 11 is disposed on the inner end face of the roller 5. One end of the line guide seat 11 is provided with a line hanging rod 12. The roller 5 comprises a pin hole 13 corresponding to the line hanging rod 12. The side wall of the other end of the line guide seat 11 is provided an arc bump 19 abutting against the side wall of the bearing 16. The rotation of the bearing 16 drives the arc bump 19 to eject the line hanging rod 12 on the line guide seat 11 out of the roller 5. A torsion spring 14 is disposed between the line guide seat 11 and the roller 5 to drive the line hanging rod 12 to retract into the roller 5. The torsion spring 14 comprises a first end disposed on the line guide seat 11, and a second end disposed on the side wall of the roller 5.

The working principle of the fishing reel is detailed as follows.

In the process of reeling in a fishing line, rotate the bearing 16, and the line hanging rod 12 is ejected and extends out of the roller 5. The fishing line on the spool 3 is wound on the line hanging rod 12. Turn the handle 8, and the first gear 6 and the second gear 7 rotate. Thus, the main shaft 4 is driven to rotate, and so is the roller 5. The roller 5 drives the line hanging rod 12 to rotate whereby the fishing line is wound on the spool 3.

In the process of reeling out a fishing line, press the release button 9, and the main shaft 4 is pushed forward. The roller 5 and the line guide seat 11 on the roller 5 are driven to move forward. Thus, the arc bump 19 of the line guide seat 11 is engaged with the second circular surface of the cam. The bearing 16 pulls back the line guide seat 11, and under the action of the torsion spring 14, the line hanging rod 12 retracts into the roller 5. The fishing line is released cycle by cycle from the spool 3 under the effect of gravity of a fishing lure secured to the front end of the fishing line. After the fishing line is reeled out, turn the handle 8, and the main shaft 4 is driven to rotate. And then the rollers 5 rotates. The arc bump 19 on the line guide seat 11 is driven to rotate. When the arc bump 19 rotates to be engaged with the first circular surface of the cam, the main shaft 4 is reset under the action of the first pressure spring 10, so that the arc bump 19 of the line guide seat 11 abuts against the outer wall of the bearing 16, and the line hanging rod 12 extends out of the roller 5.

Example 2

As shown in FIG. 4, the example provides a fishing reel that is basically the same as that in Example 1, except that: the line guide seat 20 is a square block. One end of the line guide seat 20 is connected to a line hanging rod 21. The line hanging rod 21 is disposed between the line guide seat 20 and the roller 24. A second compression spring 22 is wrapped around the line hanging rod 21. When the line guide seat 20 is engaged with the second circular surface of the cam, the second compression spring 22 is configured to push the line hanging rod 21 to retract into the roller 24.

Example 3

As shown in FIG. 5, the example provides a fishing reel that is basically the same as that in Example 1, except that: the inner end face of the roller (not shown in FIG. 5) is provided with two symmetrically-disposed line guide seats 30 with respect to the bearing; each line guide seat is provided with a line hanging rod 31; the roller comprises two pin holes corresponding to the two line hanging rods, respectively; an elastic member (not shown in FIG. 5) is disposed between each of the two line guide seat 30 and the roller to drive the line hanging rod 31 to retract into the roller.

The cam 32 comprises two first edges each comprising a first circular surface 33 overlapping the circular surface of the bearing, and two second edges each comprising a second circular surface 34 contracted towards the center of the bearing; and the first circular surface 33 is connected to the second circular surface 34 through smooth transition.

In the process of reeling out the fishing line, the main shaft drives the two line guide seats 30 disposed in the roller to cooperate with the two second circular surfaces 33 of the cam 32 respectively, so that the line hanging rods 31 on the two line guide seats 30 retract into the roller under the action of the elastic members. In the process of reeling in the fishing line, the two line guide seats 30 cooperate with the bearing to push the line hanging rods 31 extends out of the roller. The first circular surface 33 is connected to the second circular surface 34 through smooth transition. The working principle of the two line guide seats is the same as that of a single line guide seat in Example 1, and will not be repeated here.

It will be obvious to those skilled in the art that changes and modifications may be made, and therefore, the aim in the appended claims is to cover all such changes and modifications.
